2. Overview Mission Statement Milestone Product Design Specifications External Research Internal Research Design Evaluation

3. Mission Statement Design and prototype a robotic device to transport a low energy tablet to charging station for reenergizing.

4. Milestone Finish PDS Document Decide final concepts Finish BOM

5. Product Design Specification Traveling over hard surfaces and carpet. Ability to turn up to 180° Wirelessly travel up to 40 ft Easy to maintain Easy to interface the tablet to the robot Charge the tablet when docked

6. External Research Roomba Robot Pros Auto navigating system Auto detect docking and recharging 40ft wirelessly travel and 180 degrees turn Cons High cost ($350) Require extensive modification

7. External Research Line following technology Pros Low price Easy to build Cons Require specific route Not appropriate in room with many objects

8. External Research EZ – Robot Kit Pros Easy customize Friendly interface software Affordable ($218) Cons Require additional board to control motors

9. Internal Research Chassis Designs DesignProsCons Chassis – A  Extremely stable  Light weight  Limited turning Radius  Extensive manufacturing  Elaborate steering mechanism Chassis - B  Stable  Tight turning radius  Difficult to manufacture  Too many parts  Solid axle produces turning issues Chassis - C  Tight turning radius  Light weight  Simple manufacturing  Possibility for instability

10. Internal Research Tablet Holder DesignProsCons Holder – A  Easy to manufacture  No moving components  Weight  Lack of adjustability  Height Holder - B  Adjustable height  Lowered center of gravity during transport  Difficult to manufacture  Too many parts
